' up or represented by the pins in the carriage may be added or recorded.

A machine of that type is now in com- 'mercial use and 1s known as the Dalton The Dalton, adding,` machine is constructed in substantial accordance withthe addingmechanisnrof the adding' andwritingj ma 'chine illustrated in Hopkins Patent. Number 1,039,130, dated'September Q-t, 10i?, whose British` counterpart is found in British Patent Number 854 of 1904.

.e iiorconyenience of illustration and description I have shown my pr-sent invention embodied i-nan adding' machine oi` the Dalton type, but it will be apparent that the inventionis adaptable to any machine containing a movable carriage, and that many the principles of the invention are adaptable to other machines, `and i do not restrict myself to the use of the invention in any specitic adding' machine.

The adding mechanism of the machine described in the Hopkins patent above mon- -tioned contains a movable carriage having' series ot' pms arranged therein, an escapement and motor device for moving' the car ringe step by step laterally, and ascries ot' keys which are operable to set the pins in the carriage torepresent numberstobe added or recorded and to cause the escapement and mdtor device to operate effectively to` move the carriage to any desired position relative to'the adding and recording mechanisms. so that the numbers represented by the pins in the carriage may be added-or recorded. This also is the arrangement of the depart ment of the machine shown in the Hopkins Patent Number 1,039,130 and a siniilar'arrangement is employed in the Dalton7 adding machine as it is `how onv the market and known coi'nmercially. In all ot', said machines the pin carriage is moved step by step as each digit key is operated and there is no mechanism for indicating to the operator the numbers or digits represented in the carriage prior" to the` operation-ot the recording mechanism. i`herefore, should the operator operate a wrong' key, and tail to detect the error bet'ore operatiinev the recording and 'addingA mechanism, the incorrect number so set up or represented in the pin carriage would also be recorded and added; whereas, should theoperator be enabled to detect the error before. operating' the adding` and recording' mechanism, such error could be eliminated or corrected.

ii y present invention comprises mechanism loperable to indicate the items or numbers as theyA are up or represented in the pin carri-age by operation ott the keys, so that the operator will be informed at ail times what number is rt pre euted in the pin carriage, such mechanism comprising a novel registeringl device operated and controlled by the keys and the pin carriage ei tectively to indicate the digit oi cach key as it is operated, and located in plain sight. v

The register is returned to idle or clear position atthe same time that the carriage returns to idle position and moves in` unison and harmony with the plin carriage.

rilhe machine.includes a key device having` connections tor restoring the pin-carriage to idle position trom any position in which it may be located. 'it also includes a back space key whereby the pin carriage may be moved step by step toward idle position e tfet-tively to remove Jfrom registering position any one or more ot the digits rcpresentei-l in the carriageg.k .This

one or more of the digits can be removed by\ use of the back space key. The `operation ot the pm ctrriage and the register carriage is uniform in whatever direction they may move, whether in the setting up and registering of numbers, or in the correction and elimination of numbers or the digits thereof, or in their return to idle position a't'ter the adding-and-recording of numbers.

In the accompanying drawings, wherein l t. .nameift key enables the. operator to correct 'one' or more digits Cit ' have illustrated one embodiment of my invention :wFigure 1 is a view showing some of the working parts of a Dalton adding machine, and my inventionl embodied therein. Fig. E2 is a sectional View just below the key-board plate of 'the machine illustrating the item register carriage, and the connection which extends to the pin carriage to effect uniform movement of the pin carriage and the item register carriage.

Fig. 14 is a plan View showing the pin carriage escapement device, and the connections which extend to the correction key and the back space key.-

' The aiding mechanism of t'helmachine or". said Patent No. 1,039,130, and of said British Patent Number 854i of 1901, and the Dalton adding` machine manufactured in substantial accordance therewith, includes a series of ten iigures or digit keys 1, arranged in convenient relation in the key-board and having levers 2 extending rearwardly in the machine andu pivotally supported at 2a. The rear ends et said levers terminate in a longitudinalfrow and are provided with extensions constituting hammers or drivers 'for settingthe pins in the pin carriage.

y The pin carriage 1 is movably supported on rails 5, extending transversely above the key levers. Series oit pins G are mounted in `the carriage and are movable by the ham-` mers .or drivers 3 so as to represent the numbers to be added or recorded. when the An escapement shaft 7 has an arm or lever 8 attached thereto,

land a link 9 connects said arm orv lever with the carriage et, so that when the said shaft 7 is operated it will control and move 'thepin carriage. (See Fig. 2.) The series of pins l6 are thus brought into operative position with respect to the hammers 8, each step oit the carriagetransporting another row or series of'pins over said hammers. An escapcment bar 10 extends across the key levers Q and controls the operation of the shaft 7 and the other? parts connected there-y mechanism 17 effectively to cause said mechanism to add the numbers recorded. Record of the various items is made by use of type 18- on the type carriers 15 driven by ham-l mers 19. The mechanism thus described is the same as that described in the aforesaid British patent, and in the Patent Number 1,039,130, and contained in the Dalton adding machine. lt will be noted that the mechanism so far described does not include any device whereby the operator will be informed as to the value of any number represented in the carriage, or whether any number at all is represented therein..

The main shaft A controls the operation et the adding and recording mechanism. .fitter the number has been set up in the pin carriage the shaft A is rocked,'and the rod B is swung forwardly so as to permit the typecarriers 15 and-'the racks 16 te move until the depending heels 16a on the racks engage with lthe pins set to represent the number. rihe hammers 151 then strike the type 18 and print the number. The shaft A is then rocked to its initial position and the rod B' returns the type-carricrs and racks to their idle position. rlhe shaftA 4has an arm 2O carrying a pawl21. lVhen said shaft is rocked forwardly the pawl 21 becomes-engaged with a pin QQ on a link 23 whose upper endis rigid on a rock shaft 24. Return movement 'oit the pawl Q1 draws back the link 23 until said pawl is disengaged from the pin 22 near the stopping point of said pawl. rtlink 25 connects the lower end ot the link 23 with an arm 2G loose on the shaft 7, and having a lug 27 on its under side.

Isin arm 28 which is rigid on the shaft 7' has a lug 29 on its upper sidep When the linkQ is forced rearwardly the lug 27 engages the lug 28 and thereby rocks the shaft justinent ready for another operation.

7 effectivelyto return the carriage 4 to .its idle position under the plate (Figs. 2, 13 and 1 4) by which the set-up pins will be pressed'- downl to their initial or idle ad- A spring l'connecting the arm 26 with a stationary part restores said arm, the link 25, the lilik 23, and other connected parts to idle position after the pawl 21 releases said link 3. This operation is performed at each recording or adding operation, except in instances whe-re a number is repeated.

Key mechanism, commonly known as error key mechanism,7 or correction key mechanism. by which the pin carriage may be returned to idle'position without opera.-

tion of the adding or recording mechanisms, is also contained in these machines. Said mechanismcomprises a stem and key pivoted to one arm of a bell-crank lever 33 supported at 34, and a link 35 connecting the other arm of the lever with an arm attached to the rock shaft 24 (see Fig. 12). From the foregoing it is obvious that depression of thekey 52 will operate Vthe link effectively to restore 'the pin carriage to its initial or starting position and clear i or dissipate any number' set up in said carriage. A spring-actuated latch 3T is held out of engagement with the key when. the shaft A is idle, by a link leading to ay cam on said shaft. )Vixen the shaft is rocked the latch engages with the key ,39. and

prevents operation of said key while said p shaft, and the adding and recording mechanism, or either of them, are operating.

The above described error key or correo` tion key mechanism is substantially the same as that contained in the said British patent, said application Serial Number 140,300, and the said Dalton 7 machine. y1`his meehanism, it will be noted', is operable to move `the carriage to idle position, at a single operation, from whatever position said carriage may occupy. Frequentlyvit is desirable to move. the carriage only one ,ormore steps toward idlel position, todissipate or eliminate a like number of digits from the number set up or represented in the carriage. For this purpose I have equipped the machine with a back space key mechanism to move the carriage step by step toward idlel position to remove or l'eliminate one or more igures from the number in said `carriage, as desired. Said mechanism comprises a key, 39 pivoted to a bell-crank lever 40, from which a link 41 leads to a lever 42 near the rear of the machine (Figs. 1Q, 13 and 14). The lever 42 lhas pin-and-slot pivot connection with an arm 43 attached to a vertical rock shaft 44 on the upper end of which is an arm 45 carrying a pawl or dog 46 adapted to engage with the escapement segment 1l when the key 39 is depressed and move the escapement and thereby the pin carriage one step toward idle position. An abutment 47 prevents turning of the pawl or dog, and a. spring 4S holds said .pawl or dog in proper adjustment.. The latch 37 is also operative to engage with projections 49 on the key 39 and lock said key against operation when the adding and recording mechanism are in operation.

The present invention, comprising a visible item register, is embodied in and combined with the mechanism above described.

In the key-board plate above the series of keys an elongated opening 50 is formed. rIwo rails are supported below the keyboard plate and the item register or indicator carriage on said rails.` Said carriage comprises a plate 52 and two end pieces 523, and rollers 54 supporting the carriage on the rails. ik shaft 55 is supported yby the end plates 53, and the register or'indieator devices are mounted on said shaft. Said register or indicator devices are arranged in pairs, each device being substantially in the form of, thersegment of a disk, having on its peripheral edge ar flange 50. ln each pair of segments the flange of one segment operates within the flange of the other, as shown in Figs. 2 and 4. One of said flanges in each pair of registering segments has engraved thereon the figures or digits from l to 5, inclusive, and the other tlange of each pair has engraved thereon the remaining figures er dig' 0 to 9, inclusive, and 0,7 so that. the ten figures are represented in each pair of registerinlT devices. in registering the digits 1 i Q 3 4 .arrying `such figures or digits will be actushaft 5S, is connected to'said link, so that when said rock shaft is operated, the item register' carriage will be correspondingly moved. An arm at) on the rock shaft. 5S connected to an arm (50 on the escapement `shaft 7 by a link Gl (Figs. 1 and Through these connections the escapement shaft T which controls step' by step movement of the pin carriage '-t, also actuates the item register carriage, step by step from right to left with respect to the operator facing the machine. ln normal or idle position, the item register carriage is at the right., one space" or step removed toward the right from the open or registering space as indicated in Fig. 3, so that the hrst movement of the said item register carriage will position one of the registering segments in view through the open space 50. Each successive movement of the item registering Icarriage positions another one of the regisfio the item registering carriage being in conformity with the lateral sten by step movement of the pin carriage -i in which the numbers that are to be added and recorded are sot up or represented by operation o the k ys l. ln normal or idle position the registering segments are 4held in a forward adjustment so that all of the ligpires or digits thereon, except thefc O, are below and concealed by the plate 52. iilhen any numeral or digit 'key is operated, the corresponding registering segments will likewise be operated to present the proper figure or digit in view through the open space .50. rlhis movement is etl'ected by suitable connections whereby each key will operate the corresponding registering devices in proportion to the value of the key.

riwo alined shafts G2 `and G8 are supported in bearings under the keys. The shaft, 62 has forwardly extending arms (Bil which support a rod G5 and theshaft G3 has forwardly extending arms GG which support a. rod G7. Springs G8 (il 5) connect depending'arms 69' on the shai'ts G2 and G3 with the stationary part of the machine and are eect'ive to uphold the rods 65 and 6T close to the lower edge of the key levers. The levers for the l 2 3 d 5 extend over the rod 65 and are different distances `from-said rod in proportion to the value ot the keys-*that is to say, the l key lever is nearest the rod G5, the 2 key lever is a slight distance removed therefrom and the key levers for the figures 3 il an( 5 aro at4 increasingly greater distances 'from the rod 65. ill-hen the l key is depressed the rod G5 will be pressed down- 'ardly an equaldistanee and the shalit (32 will be coi-respondingly rocked, whileoperation ot the 2 key will rock the shaiit G2 a distance less than does the l key7 corresponding to the diiiierence in value between tl e two digits. This difference in, the motion imparted to the shaft by operation et the digits keys is maintained by all of the digits-keys .vhich atleet 4said shaft so that the 5 l key will rock sa/id shaft only a very slight distance, much than does the l key, for instance. rlhe levers for the (3 l, T d, and keysy are similarly arranged with respect to the rodl G7, and rock the shaft G3 dilierent distances conitorming to the value or the keys depressed. The shafts G2 and (323 transmit this mffion to the rt 4 tering segments in the item register carriage, and since no motion is' required to register the i O-27 in sight through the, open space 5G, the O key causes no motion ot the item .register device except lateral movement to the item register carriage which is transmitted thereto from the lateral n'iovement of the pin carriage 1l.

rlhe shaft 62 has an upwardly extending tering segments in view, such movements oit.

ret/cesa arm 'i0 to which is pivoted a bar or link 71, the rear end ot which has an elongated slot 72 through which projects a square supporting rod T3. The shaft 33 has an arm 7e'- similar to thearm TO and a link or bar 754 similar to the link or bar 7l, and likewise supported ou the square supporting rod 73 2 and G). Each o the bars orlinks 7l has pivoted thereto a number of links 7G which supporta rack 77 anda pawl 78 is pivoted to each rack i7 and is permitted a slight vertical n'iovement by a pin 78 on the rack extending into a slot S0 in the pawl. in idle position the front ends ot' the pawls abut vagainst the supporting rod 73permitting the racks T? to rest in their lower adjustment shown iu Fig. 5.

Each registering segment has anarcuate rack 81.011 its lower edge, said racks being in a plane just above the racks 77. The -arrangement is such that the racks 81 on these registering devices containing the digits l l to 5 inclusive are moved successively and. positioned immediately over that rack 77 which is onthe bar or link 7l which, as previously described, is actuated by the keys l to l inclusive. Similarly, the racks 8l on the registering devices containing the digits G to 9 inclusive (and the l O character) are moved and positioned successively over rack 77 which is carried by the bar or link which,.as previously described, is operated by the keys G. to 9 inclusive. When any digit key is depressed and its bar or link 71 or 75 is moved forwardly the pawl 78 by engagement witlrtlie si-ipporting rod Z3/raises the rack 77 until it .mesheswith-the rack 71 immediately thereover. An, abutment S2is on each link or bar 7l and 75 I(Figs. 5 and 10) and is brought against the rear end of the rack 77 by the Jforward movement of" the link or bar il and 75 when said links or bars are so operated. At the time of said engagement of the abutment 82 with the rack 77 the pawl 78 is above the supporting rod 73 so that the rack 77 now in mesh with its proper rack 8l will be moved forwardly a distance correspoiiding to the value of the key depressed and will transmit proper motion to the registering segment in the item register carriage. This motion is sutlicient to position the digit on the registering device so operated in view through the open space lhen the keys are released the shafts T2 and 73 are returned to idle position by their springs T8 which also return Athe links or bars 'Tl andT to the racks 77 carried thereby. lt will be observed that the racks T7 during their backward movement do not operate the registering devices, but are lowered by gravity to their idle positions disengaged from such registering devices.

The registering segments have arcuate slots S3 and the side plates 53 ofthe item said teeth to latch said segments in register' .mg posit-ion at the proper time.- rllhe first ope-ration of a key causes the pawl 85 at the lett to engage With and lock the proper registering segments, and releases the next one et the paivls 85 by moving it past an oblique shoulder S9 on the plate or bar` 86. Since one of the registering segments is positioned .by the key-at the same time the paivl at the left Will ei'igage with the-teeth 87 on the registering segment so positioned and hold it in suchl position so that the iigure or digit thereon corresponding to the key operated Will be presented to view through the open space 50. The ho'ok 88 on each pawl 85 is long enough to engage With the teeth 87 ot both members of that pair of registering segments With which. said paivl cooperates and a spring 90 is provided to actiiate each registering segment to its idle position when released from the pawl. A spring` 91 actuates the paivls S5 so as to engage them with the teeth of the registering segments when lsaid paWls are released' from the bar 8G by movement of the item register carriage, as above described. Each registering segment operated will thus be latched and retained ,in registering position when operated. ritter each number set up or represented in the pin carriage 4 is addedor recorded said carriage is automatically returned to idle posit-ion, as hereinbetore described, which movement rocks the escapement shaft 7 and operates the arm 60 attached to said shaft; nection Jfrom the arm '60 to the item register carriage alsov moves said carriage to its idle position at the right of the machine with respect to the operator, and this movement of theitein register carriage releases the registering segments in said carriage and permits them to return to idle or clear i adjustment in the carriage; l/Vhile the item register carriage is moving toward'its idle position the rear ends of the paw'ls `85 move along under the bar 86 toward the oblique' shoulder 89 on vsaid bar and just prior to .rubbing'against said shoulder each pawl engages a shoulder'92a on a trip plate 92 which is yieldingly supported by the bar 86. Said plate has oblique slots 93 through which extend pins orv studs 9i supporting said plate on saidibar 8G. v A spring 95 connecting said plate 92 with the bar 86 holds said plate' 92 vin its `highest.position unt-il engaged by the The con-l end of a pawl 85 moving toward idle position: `Wlien any one of the pawls S5 engages the shoulder 92a'oii the plate 92 during` the movement of said'paivl toward idle position v it has the eiiect of moving` said plate 92 obliquely downward ivhich also presses doivii- Wardly 'the rear ends of the two pawls engaged therewith. This movement is continued until the end of the paivl nearest the oblique shoulder S9 passes under the Wider portion ci' the bar 86, at which time the plate 92 is released and restored'to idle position by its spring 95 ready to be engaged by the next. adjacent pawl.

v It will be noted that the last or lett hand paivl S5 does not pass lunder the plate or bar S6, but remains in the position shown in Fig. 6, said paivl having been released from its registering seginent'by the movement ot the plate 92 caused by the previously returned paivl. u

A series of arms 9T are attached to the shafts G2 and G3 and extend alongside ot the levers 2. Abutinents 9S are on the levers 2 and receive the impact of the arms 97, and thereby prevent excess movement or rotation ot the said shafts 62 and 63 so as to assure correct operation ot -thze registering segments. n

. YVhenever the pin carriage et is returned to its idle position Without. adding or recording any number tnat. may have been set up or represented therein by operation of the correction mechanism or the back space mechanism, it is plain that the item register carriage will also be moved toivai'd idle position to clear therefrom one or more of l the digits, ortho entire number, as desired, depending on whether the correction key or the back space key be operated. Thisitem register mechanism and the pin carriages in which the numbers are set up or represented preliminarily to adding or recording them, are connected sotliat their operation is uniform throughout. rEhe top plate 52 is preferably prorided with a series of openings or holes 9G through which the registering seg- -inents and the numeral or digits thereon ivill be visible as shown in Figs. 3 and 5.

l have shown the item registering mechanism actuated directly from the keys and lo- -v cated just above the key-board in convenientposition so that the operator may readily observe both the keys and the registering mechanism While operating` the machine. I do not. restrict myself to this arrangement, since the registering mechanism is readily adaptable vto other embodiments. and may be located in any preferred position.v I ain aware that there may be variousinoditications -in the construction, arrangement and operation of ,the various parts Without the least departure from the nature and principle of my invention, and l do not restrict myseltto specific devices, but l ilo iso
